Answer:
{x\ x e U and x has a negative square root} is an empty set.
Step-by-step explanation:
If x e U, x is a negative real number, and they don't have a square root (they don't have even roots). Their square roots are complex numbers, not real ones.
Pennies Toby has = 178
Pennies Bella has = 190
Hence, Bella has more pennies by 190-178=12
Bella has 12 more pennies than Toby.
